SpIES: Infrared Source Catalog from Spitzer Space Telescope Survey

115 square degrees of the Equatorial SDSS Stripe 82 field were surveyed by the Spitzer IRAC Equatorial Survey (SpIES). The catalog from NASA contains millions of sources detected at 3.6 and 4.5 microns, achieving 5 sigma depths of 6.13 and 5.75 microJy, respectively. It was last updated on 2026-03-13.

Use Cases

• Identify and catalog infrared-only sources based on the 3.6 and 4.5 micron detection bands.
• Study galaxy populations and star formation in a large-area equatorial field.
• Cross-match sources with other surveys like SDSS Stripe 82 for multi-wavelength analysis.
• Train machine learning models for astronomical object classification using infrared photometry.

Strengths

• Covers a large survey area of 115 square degrees.
• Achieves precise 5 sigma depths of 6.13 microJy (3.6 microns) and 5.75 microJy (4.5 microns).
• Contains millions of sources across single-band and dual-band catalogs.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is stored in a BIN format, which may require specialized tools for access.
